GEORGE KLEIN, or MEDINA, NORTH DAKOTA.

THRE SHING-MACHINE To all whom it may concern:

Be it known that I, GEORGE KLEIN, a citizen of the United States,residing at Medina, in the county of Stutsman and State of North Dakota,have invented certain new and useful Improvements in Threshing-Machines,of which the following is aspeciiication.

This invention relates to threshing machines, and has for its object toprovide a machine of this nature which will be extremely simple andwhich will be constructed to separate the loose grain from the strawwithout the use of beaters or other similarly operating mechanism.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the speciiicstructure shown and described may be made within the scope of the claimswithout departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a longitudinal section through a threshing machineconstructed in accordance with the present invention, Fig. 2 is a topplan of the mechanism, Fig. 3 is a section on line 3 3 of Fig. 1 showingthe retarding plate.

Referring now to the drawings, the present invention comprises a bodyportion 5, in the forward portion of which there is mounted atransversely extending threshing cylinder 7 having a concave 8 locatedtherebelow.

An upwardly and rearwardly inclined shaker 9 is arranged to receivestraw from the rearward side of the concave, and a second similarlyarranged shaker 10 is arranged to receive straw from the rearward end ofthe shaker 9. Located beneath the shaker 10 there is a downwardly andforwardly inclined grain return pan 11 discharging upon a longitudinallyreciprocating bed 12 arranged to discharge upon a sieve 13. A trunk 14contains the sieve 13, the latter be ing also mounted for reciprocatingmotion, and located at the forward end of the trunk there is a blower15. The trunk has a downwardly and forwardly extending bottom 16emptying into a transversely inclined discharge spout 17.

Located within the upper portion of the bodyA portion 5 rearwardly ofthe cylinder 6, there is a downwardly and rearwardly inclined,transversely extending retarding plate Specification of Letters Patent.

18 having its lower edge curved rearwardly as indicated at 18 and lyingin close relation to the shaker 9. As will be seen from the drawings,this plate 18 will be engaged by straw from the cylinder 6 and concave8, to retard, the straw in its passage over the shaker 9, thus insuringa maximum agitation of the straw to separate the loose grain therefrom.

From the shaker 9, the straw passes to the shaker l() and thence fromthe rearward end of the machine, the return pan 11 receiving loose grainfrom the straw upon the shaker 10, and discharging such grain on to thebed 12.

From the bed 12, the grain passes to the sieve 13, where chaff and otherwaste matter is separated therefrom by the blast from the blower 15, thegrain passing from the sieve to the bottom 16 of thet trunk, and thenceto the discharge chute 17.

At the rearward end of the trunk, there is a discharge chute 19 locatedto receive matter too large to pass through the screen 13, and too heavyto be blown therefrom, it be ing understood that the screen is mountedfor reciprocating motion to discharge such matter from its rearward end.

The retarding plate 18 is provided at its upper end with an attachingportion 20- which is formed by bending a portion of the plate at rightangles, and this portion of the plate is thus disposed above thethreshing cylinder 7 and may be attached to the top of the body portion5 in any convenient man ner. By the arrangement ofthe curved lower endof the plate 18 it will be seen that a lip 18 is provided which extendsupwardly and toward the rear of the body portion 5, as shown. Theprovision of this lip 18 is such that straw will jam there against in areturn movement of the shaker 9 to hold the straw between the curvedportion 18 and the shaker 9 and thus insuring a thorough agitation ofthe straw.

The straw etc., is very gently Vgrasped and detained between the smoothconvex edge of the deflector and the carrier, the teeth of which pullaway and thin out the straw to permit escape of grain.

What is claimed is:

The combination in a threshing machine, of the frame and casing, thethreshing cylin der and concave, and the reciprocating straw carrierhaving a serrated working surface, and a deiiecting plate having a bentupper edge whereby it is secured to the frame, an pulled away by theserrated surface of the inclined surface facing the threshingrneohancarrier to permit the esoape of the grain. 10 ism, and a loweredge curved to form a con- In testimony whereof I afliX my signature,Vex surface engaging the straw ete., as itis in presence of twowitnesses.
